IMPROVEMENT IN sAsH-FASTENERS.

Speciiication forming part of Letters Patent No. 35,489, dated June 3,1862.

To all whom/ may concern.-

` Be it `known that I, HERVEY S. PHILLIrs, of Westfield, in the countyof Hampden and State of Massachusetts, have invented Improvements inSash-Balances, of whichthe following is a specification.

Said improvements consist in the combination of two racks, one of whichis secured to the upper sash and the other adjusted to the lower sashinthe manner hereinafter set forth, with the cog-wheel, fastener, andcatch, the whole being arranged aud operated'as hereinafter described.

In the drawings, Figure lis a side elevation of a window with y myapparatus attached. Fig. 2 is a longitudinal section of the frame ofsaid window. Fig. 3 is an edge`view of the two 'sashes with the racksand cog-wheels shown. Fig.etisan-side-elevation in detail of a portionof the lower sash, showing the fastener drawn in, so as to allowtherac'k to slide up. Fig. 5 is a view in detailrof the catch.

`The object of this improvement is to obtain the means of raising andlowering either or both sashes of, a window in an easy manner and by asimple combination of mechanical devices, so that it can be applied tothe windows of public buildings and pri vate residences without muchliability of getting out of repair, and at a moderate cost. By means ofthis improvement, also, the sashesi may easily be removed for thepurpose of washing them, which it is very diliicult todo when the cordand weights or the cord alo ehsed. In the case of the cord and weighfsthere is a constant wear of the cords, which makes them liable tobreak at anytime, making it necessary 'to remove the sash and one sideof the weight box before the damage can 4be repaired. Where the cordsare used alone, the same objections hold good in' part, besides, thecords being very likely to stretch and let the upper sash down when thelower one is shut. The expense of this is also greater than that of theinvention underlconsideration. `In this improvement both sashes may besecured by means of one fastener in a very edicientmanner.

l is the frame of the window; 2, the upper sash, and 3 the lower sash. 4is the rack of the upper'sash; 5, that of the lower sash. Gis thecog-wheel. 7 is the fastener, and 8 the catch. y

The rack 5 is secured to the sash by means of a bracket, 9, which isshown in dotted lines in Fig. 1 and more plainly in Fig. 4;. The pin 10passes through the slot inthe bracket, and

thus while it holds the rack in position at the same time allows it toslide up and down. There are holes 13 in the rack 5 for the fastener 7to fall into and play through for the purpose of fastening the sash atany desired point, and also to prevent the independent movement of therack when 'it is not desired.

lf it is desired to let down the upper sash without raising the lowerone, the fastener is drawn out, as shown in Fig. 4, and the upper sashdrawn down by hand, the rack of the lower one moving up at the sametime,instead of the sash; or, if preferred, the lower sash may be pushedup without disengaging the rack, which will draw the upper one down.Then by pushing the fastener up and disengaging it, as in Fig. 4, thelower sash may be let down.

If it is desired to put both sashes up as far as possible, the lowersash is first pushed up, (drawing down the upper one half way.) Then theupper one is pushed up also until the spring shown at 11, Fig. 2 catchesinto the notch 12, Fig. 3.V The spring 11 is just sufficiently strong tohold the sash up, but not strongenough to prevent its being pulled downby the hand. After the sashes have been put into this position the upperone is drawn down tirst in shutting the window.

When the upper sash is half down, the lower sash may be adjusted atdifferent heights by means of the fastener 7, passing through the holes13 iu the rack 5 and entering notches made to receive it in thewindow-frame. The upper sash is never drawn down more than halfway,being stopped by the block 14, Fig. 2.

The catch 8 is intended to prevent the fastener from being thrown up sofar as to free the rack 5, and th us let the upper sash down tooviolently.

The combination of the rack 4 and cogwheel 6 with the rack 5v andfastener 7, constructed and arranged in the manner and for the purposehereinbefore set forth.
